Collaboration of audio sensors for geo-location and continuous tracking of multiple users in a device-independent artificial intelligence (AI) environment

ABSTRACT

Audio sensors collaborate for geo-location and tracking of multiple users. Different users can be independently geo-located and tracked within the AI environment. Location is determined from two or more AI clients of known locations that detect an event such as a human voice command to connect a call with a specific user. Responsive to classification of the event in view of the estimated location, a command for an AI action, such as connecting a call between users, is received for a response to the event at the AI clients that detected the event, or others.

FIELD OF THE INVENTION

The invention relates generally, to computer software, and more specifically, to a collaboration of audio sensors in an artificial intelligence (AI) environment to identify and continuously track multiple users.

BACKGROUND

Home AI refers to various levels of automation for appliances and electronics in homes, businesses, automobiles, and other environments. Many conventional systems provide low levels of automation, and are closed to a predefined list of commands. For example, a coffee maker can be programmed to brew coffee at a certain time, lights in the home can be turned on automatically due to low lighting conditions, and power to electronics can be “clapped” on or “clapped” off. Also, smoke detectors and thermostats can perform certain actions based on certain direct instructions.

With the addition of networking, home automation devices can send alerts through a network. For instance, a conventional security system or fire detection system can send alerts through a network because of an intrusion or fire emergency, respectively. Other types of automation operate according to voice commands when a button is pushed to activate the voice command mode, such as on smartphones and in automobiles.

Problematically, conventional home AI fails to distinguish between multiple users in a common environment, at the same time. In some conventional systems, commands are processed without any voice analysis, thereby treating all users together as a single user. In other conventional systems, a user is logged in, so commands are processed as all coming from a single identified user. The lack of identification limits personalization levels for AI interactions in conventional systems. But it is inconvenient, and unnatural, in a multi-user environment for users to constantly identify themselves.

Further, smartphone-based AI (e.g., Siri by Apple Computers of Cupertino, Calif.) and other hardware are device dependent, relying upon users carrying around and intentionally interacting with the smartphone or a specific piece of hardware. In particular, smartphone calls between two persons typically requires that a smartphone dialer application be initialized, a telephone number located and dialed, and continued possession of the smartphone throughout the telephone call. The calls are limited by battery life of the smartphone. Moreover, the smartphone AI functionality is not currently available in the home or business environment.

Another smartphone-based AI that relies upon users carrying around a physical device is location services. A user is assumed to be located proximate to the device which provides a location using GPS coordinates of the device.

What therefore is needed is a technique that locates and tracks multiple users within a device-independent AI environment. Location information should enable various applications, such as easily initiating and connecting device-independent telephone calls between the multiple users.

SUMMARY

To meet the above-described needs, methods, computer program products, and systems for collaboration of audio sensors for geo-location and tracking of multiple users in a device-independent artificial intelligence (AI) environment, such as home, office, outdoor area, or business.

In one embodiment, location information is stored for each of the plurality of geographically-dispersed AI clients. Each of the AI clients can include an audio sensor, a network controller, and a feedback mechanism (e.g., a speaker or an LED) within a common enclosure. Responsive to detection of an event (e.g., involving a human, machine, or ambient condition) at two or more of the plurality of geographically-dispersed AI clients, audio event data is centrally received from audio sensors of the two or more of the plurality of geographically-dispersed AI sensors. For example, a user can speak a command for turning on lights while walking down a flight of stairs that is detected by one AI client at the top of the stairs and one at the bottom of the stairs.

Different users can be independently geo-located and tracked within the AI environment. Identification data can be applied to events to distinguish one user from another, including voice prints, habits, walking patters, and the like. As users move around an AI environment, new events are detected at new AI clients, which are processed to update location. A location of users involved in a call is estimated based on the location information and the audio event data (e.g., triangulation). Responsive to classification of the event in view of the estimated location, a command for an AI action, such as connecting a call between users, is received for a response to the event at the AI clients that detected the event, or others.

Advantageously, the user experience with AI is more natural because the AI is not dependent on users carrying around a device for location-based AI interactions, such as calls between users.

DETAILED DESCRIPTION

To meet the above-described needs, methods, computer program products, and systems for collaboration of audio sensors for geo-location of events in an artificial intelligence (AI) environment, such as home, office, or business, as described herein.

I. Overview of Features

The scalable AI, command-control system is an adaptive AI that can learn the habits of one or more individuals and one or more environments for a better user experience. As a result, actions taken by the AI system become more accurate over time. Microphones and speakers distributed in consumer appliances around the home allow natural voice interaction without a physical device needing to be worn or held. Each consumer appliance can also be outfitted with a feedback mechanism, such as an LED light, a speaker, a buzzer or display, and even feedback on a separate device. Other sensors on consumer appliances can collect data about the household for storage in a database.

Advantageously, users can perform normal tasks around the home as the present AI system tracks patterns and learns behaviors to automatically make those tasks easier using prediction algorithms (e.g., automatic lighting based on user movements, detection and notification of house activity via SMS). Exceptions to predicted actions can raise red flags (e.g., identification of medical emergency). Users can interface with the AI system by talking naturally for hands-free control and management for non-automated voice commands and interactions (e.g., lights come one automatically, and user requests a certain color or intensity as a modification). The AI system acts as an assistant (e.g., notifying user of incoming calls or guests). Users can retrieve public and personal information from the cloud (e.g., sports scores, bank account balances, Facebook statuses, etc.), make purchases (e.g., using Amazon.com APIs), enter new calendar appointments (e.g., using Google.com APIs for calendar application), and the like.

The system can also provide feedback to users. Sounds and lights can confirm commands and communicate modes of the system (e.g., voice response stating “your order will be delivered Friday” or green blinking LED). The examples of this description are merely illustrative and are not intended to be limiting as one of ordinary skill in the art will recognize many variations consistent with the spirit of the inventions as specifically described herein.

Home automation, as referred to throughout the description, should be understood to be an exemplary environment. Other environments include offices, automobiles, business, wearables, parking lots, shopping malls, gyms, libraries, hybrid environments, multi-system environments, and the like. Consumer appliances and electronics refer to just a few categories of devices that can be manufactured for, or retrofitted to plug in to, the AI system. Also, users can be owners of the systems, or employees, guests, customers or others that interact with the systems of others.

II. Systems for Home Automation Using Sensors on AI Appliances

FIGS. 1A and 1B are schematic diagrams illustrating perspective views of an AI appliance 100 in the form of wall outlets, according to one embodiment. The AI appliance 100 modifies a traditional wall outlet to a provide AI with a plug 110 for insertion into an electrical outlet receptacle at one end and a receptacle 120 for an electrical appliance, to be controlled by the AI appliance 100, to plug in to an opposite end. An enclosure 130 can be composed of plastic, rubber, or any appropriate material. A button 140 on a top side of the enclosure allows manual controls such as power on, power off, and reset. A colored portion 150 of the enclosure covers an LED light to give a user visual feedback to events detected by sensors. Some AI appliances modify existing traditional appliances (e.g., over wall outlet as 100) while others integrate existing traditional appliances (e.g., in wall outlet installed into the drywall (not shown)).

An exploded view of the AI appliance 100 in FIG. 1B exposes a motherboard or printed circuit board (PCB) 160 used to implement AI circuitry. Sensors, a transceiver, antennae, a central processing unit (CPU), a power supply and/or power controller, memory element, or other electronic components can be attached to the board (see e.g., FIG. 2). Many other types of appliances can be AI appliances as described herein.

In the case of calls between users, the AI appliance 100 is one of many sensors distributed around an AI environment. The AI appliance 100 can detect events used in collaboration with other appliances to geo-locate the users. The AI appliance 100 can also provide a microphone and a speaker for conducting calls in collaboration with other appliances. Many different applications can be implemented on the geo-location platform, conducting geo-location enabled calls between multiple users is just one of those applications.

FIG. 2 is a block diagram illustrating an AI appliance 200 (or AI client), according to one embodiment. A sensor engine 210 collects raw data that is analyzed by a centralized AI server, at times in aggregation with raw data collected at other locations. The present embodiment includes a video sensor 212, a motion sensor 214, an audio sensor 216 (e.g., a microphone for conducting a telephone call), temperature sensor, humidity sensor, gas detector and an ambient light sensor 218. The sensors continually collect data in a temporary memory, in one embodiment, that can be framed and transmitted as a file upon detecting an event (e.g., MP3 file or MP4 file). The present configurations of sensor are merely illustrative and can be implementation-specific. The AI appliance 200 can be implemented with both analog and digital electronic components, including conventional components such as a processor and other components necessary for operation (see FIG. 10).

A transceiver 220 transmits the raw data collected by sensors to a centralized AI server and/or other external resources. Complementary software components can be provided such as IP protocol stack software. The transceiver 220 can operate in accordance with protocols, such as Wi-Fi, Bluetooth, an electrical outlet protocol, or any other type of wireless communication standard. Optionally, a Bluetooth 4.2 or other type of radio can provide Bluetooth beacon tracking to assist in location determination.

A speaker/LED 230 allows the system to provide feedback to users for AI actions. Additionally, speakers output sound for telephone calls or multimedia playback. Computer generated voices can ask questions concerning predicted actions or respond with confirmations of an event. An action with one AI appliance 200 can be confirmed with feedback at a different AI appliance 200 responsive to movement, location of user, or feedback capability (e.g., an AI appliance with a speaker may take over feedback if the initiating AI appliance only has an LED light and voice feedback is preferred). Alternatively, the confirming action initiated by one user may concern a different user that is detected at a different location. Numerous forms of chirping, blinking, and the like can be implemented.

Appliance components 240 can be any traditional components for operations for the appliance. For an AI refrigerator, the appliance components 240 include a condenser and fan. For a wall component, the appliance components 240 include a receptor and terminals circuit connections. In some cases, the appliance components 240 have feedback to the AI components for functions such as power consumption monitoring, on/off toggling, and the like. In some embodiments, a traditional appliance is converted to an AI appliance, for example, by using an outlet that is an AI appliance.

FIG. 3A is a block diagram illustrating a system 300 with AI appliances 310A-C coordinated for providing home automation, according to one embodiment.

Event 301 occurs at a location in an AI environment within range of sensors on AI appliance 310A and AI appliance 310B. Events can originate from human commands, human activities, machine activities, ambient conditions, or the like. As a result, more than one AI appliance collects sensor data for analysis. In one embodiment, the analysis geo-locates event 301 based on sound intensity and known locations of sensors. With a third sensor located at a third location, the accuracy increases as the third input allows a triangulation of sound intensity. In another embodiment, motion sensors or video cameras are used for geo-location. In other embodiments, chemical analysis and other ambient measurements are taken at different locations for analysis.

Event response 399A and 399B occurs, in this embodiment, at a location distinct from events 301A and 301B, respectively. For example, a user enters a home at event 301 and a coffee machine (e.g., plugged into AI appliance 310C) turned on at event response 399. Alternatively, event response 399A and 399B, as well as events 301A and B, can take place at other locations.

One example of an event and event response occurs in the context of establishing a call between users. As shown in FIG. 3B, user 302A and user 302B are located in the AI environment, as defined by AI appliances 301A-C. User 302A issues an audio command such as “Call Laila” as event 301A. Both AI appliance 310A and 310B are within audio range of user 302B, so both pick up the voice command. Volume (or intensity) is one factor that can be used to determine whether user A 302A is close to AI appliance 310A or 310B. A third AI appliance would allow for triangulation for a more precise location. AI appliance 310C may pick up trace audio for use in triangulations, but some sounds may below a required threshold for use. Additionally, more than three data points may be available.

Besides location triangulation, multiple microphones can pick up the same voice command. The additional samples from different locations, in combination, help isolate a higher quality

A last known location of user 302B may already be known from event 301B, which could be a direct interaction or an observed action such as washing dishes. The last known location can be used as an initial contact attempt to user B 302B as an event response. One or more AI appliances proximate to event 301B can call out Laila's name to confirm or update location. Once located, a call is connected between users 302A and 302B. One embodiment balances speaker and/or microphone volumes on AI appliances based on user location. As either location changes, speaker and/or microphone volumes can be rebalanced, as a response.

In some embodiments, location can refer to a location of digital activity, for example, a location can be an SMS application, a social networking web site, smartphone location coordinates, or anywhere that a user can be reached. For instance, an SMS message can be sent to a user with a link to connect to a call conducted by an AI controller.

Privacy features can also be automatically implemented. For example, if several people are recognized within audio range of a call if connected, a human voice interface can offer to take a message or to set up the call in a different room or even transfer the call to a telephone device.

FIG. 4A is a high-level block diagram illustrating a system 400 for providing home automation using an external network 405B, according to one embodiment. The system 400 comprises an internal network 405A coupled to the external network 405B via the network 499. The connections can be wired, wireless, or a combination of both using mediums such as the Internet, 3G/4G cellular networks, analog telephone lines, power lines, or the like.

The internal network 405A can represent a home, business, automobile, or combination of environments connected by a local area network (LAN) or another network. The internal network 405A includes AI appliances 410A-C and an AI gateway 420. The AI appliances 410A-C can be any consumer appliance or electronic device appropriate to integrate with the system 400. The AI appliances 410A-C in some embodiments are thin devices that rely on the AI gateway 420 for access to the external network 405B. Examples include wall plugs, over wall outlets, lamps, scones, switches, smoke detectors, home appliances (e.g., toasters and microwaves) and the like. More AI appliances and sensor improve AI performance. The AI gateway 420 accesses the external network 405B using, for example, a MAC card, a Bluetooth radio, an IEEE 802.11 wireless card, or the like. The AI gateway 420 can be a dedicated box, an application executing on a PC or network device, or an AI appliance acting as a master to other slave appliances. Also, the AI appliances 410A-C can be communicatively coupled in a mesh network, such that one AI appliance proxies as an access point for another. In another example, one device may have a Bluetooth connection only, and need to proxy through a device that is connected to the AI gateway 420 through an Ethernet connection.

The external network 405B can represent resources available through the network 499. The external network 405B includes AI server 430 and external resources 440A-C. The AI server 430 provides centralized management of the AI appliances 410A-C and processing of input from one or more sensors of one or more AI appliances 410A-C. The external resources 440A-C can be accessed by the AI server 430 on behalf of the AI appliances 410A-C. The external resources 440A-C can be, for example, online applications such as Pandora, Facebook, Google Search or Google Calendar.

In one example, event 451A is caused by a user requesting a calendar entry or song purchase from iTunes. The user is located proximate to the AI appliance 410A but may also be detected by audio sensors located further away on one of the other AI appliances 410B-C. The AI server 430 in this example, could geo-locate the user based on the amplitude of sound detection at the various sensors. With knowledge of a location, lights or other electronics can be activated in accordance with a user in that location. The AI server 430 could also recognize the user and activate electronics or trigger an event in a manner that is customized to a particular user.

In another example, event 451B is caused by an ambient condition such as a washing machine buzzer detected by one or more sensors. When a sound clip is received at the AI server 430, a local database or an external database can be searched in order to identify the event. Once identified, an appropriate event response can be executed. One event response can be a message displayed on a television detected as being on. Another event response can be an SMS message or an e-mail message that is automatically generated to include a description of the identified event and sent to a user.

The system 400 can have many variations, with more or less components, such as a system of AI appliances that are peers and share date between themselves, and AI appliances that are autonomous in that they individually connect to the AI server 430 or the external resources 440A-C. One implementation provides various levels of encryption. Another implementation includes a mobile user device (not shown) connected to the network 499, such as a smart phone, a tablet device, a laptop or even a stationary PC. The mobile device can be used as an additional AI appliance that interacts with the system 400 from within or outside of the environment. Additionally, sensor data and event feedback and confirmations can also be sent to the mobile device. Moreover, the system 400 can connect to outside AI systems (e.g., two different office locations, or a user's home and automobile).

FIG. 4B is a block diagram illustrating types of calls over the system 400 of FIG. 4A. The types of calls include, without limitation, an in-network call, a network-to-network call, and an external network call. Other call categories are possible.

The in-network call is shown as route 1 and can be defined as a call in which both users are under a common AI gateway. Route 1 starts at one or more AI appliances receiving voice data 410C, that in turn is sent to the AI gateway 420, and is finally sent to one or more AI appliances 410A for audio output. Because of the architecture, the AI gateway 420 is able to control call routing. Policies and preferences can be enforced from end-to-end. Quality of service can be more predictable because more comprehensive network metrics are available.

The network-to-network call is shown as route 2 and can be defined as a call in which both users are under differing AI gateways. Route 2 starts at one or more AI appliances 410C receiving voice data, that in turn is also sent to the AI gateway 420, which then routes voice data to an external AI gateway (not shown). Both AI gateways can be on different LANs, separated by a WAN, and alternatively, can be on the same LAN. But the AI gateways can be of a common manufacturer, use a common protocol, or be otherwise compatible in techniques for internetwork call routing.

The external network call is shown as route 3 and can be defined as a call in which one user is not under an AI gateway. Route 3 starts at one or more AI appliances receiving voice data, that in turn is also sent to the AI gateway 420, which then routes voice data to an external resource. In this particular implementation of FIG. 4B, the AI server 430 serves as a remote service to connect the external call to the external resource. In this case, a call may be routed to an external network, such as a cellular network, Skype, Google Voice, or any other voice communications network. A call to a non-human artificial agent either in the form of a virtual assistant or chat bot. For example, if a person wants to buy soap it calls Amazon Alexa virtual assistant, however if a user wants contact info prior to a business meeting it calls Microsoft Cortana.

III. Methods for Providing Home Automation Using Sensors on AI Appliances

FIG. 5 is a flow diagram illustrating a method 500 for providing home automation using an AI appliance, according to one embodiment. The method 500 can be implemented in any of the devices discussed above.

An event is detected through one or more sensors of an AI appliance (step 510). For instance, an audio sensor can have a volume threshold that defines an event once exceeded. A duration of an event can span an entirety of time that the volume remains about the threshold. The duration can also span a predetermined amount of maximum time. In some embodiments, constant or long-term sounds can be ignored or filtered. An event as defined by one sensor can define an event for another sensor. For example, if an audio event is detected, a bio sensor or temperature sensor can collect data over a corresponding duration, in order to provide a more robust response.

Sensor data is sent from the event to a resource for analysis (step 520). The analysis can occur at a local, or cloud-based server, or at a master AI appliance. The analysis interprets the event in order to determine an event response. A table or default or customized commands can be stored for correlating an identified event with a response sent back to an AI appliance. Certain events can be configured. For example, a new stove or alarm clock can be added through a user interface, causing a manufacturing download of sounds to be added to a database.

In some embodiments, an AI server accesses an external device for a query or other interaction with remote applications. Results can be sent back to the AI server or directly back to an AI appliance.

A command is received for a response to the event based on the analysis (step 530). The response to the event is executed and/or feedback is provided to the user, at the selected AI appliance (step 540). For example, an online music service is activated responsive to an event of a user asking for music. An LED light or voice can communicate a successful transaction. The music service can involve a first device while the LED light or voice feeds back at a second device, in some embodiments.

FIG. 6 is a flow diagram illustrating a method 600 for coordinating multiple sensors to provide home automation using AI appliances, according to one embodiment.

An event is detected through different sensors at one or more AI appliances at a known location (step 610), as discussed in more detail below in association with FIG. 7. The locations can be preconfigured or determined using GPS, Wi-Fi triangulation, or other location technologies. In an embodiment, the layout of an environment including AI clients and other features (e.g., stairs, doors, bathrooms, etc.) are programmed by using a smartphone with location technology to take a location snapshot while also allowing a user to enter a description or scan a QR code or another identifier. The geographically-dispersed AI appliances are shown and discussed above in association with FIG. 3. The different sensors can also be embedded in a single device.

Multi-sensor data from the event is sent to a resource for analysis (step 620). The multiple perspectives afford a better characterization of events such as geo-location. A 3-dimensional data set forms from multiple inputs that traditional systems merely receive as linear data.

A command is received at a selected AI appliance for a response to the event based on the analysis of multi-sensor data, i.e., a response command (step 630), as discussed below and illustrated in FIG. 8. The response to the event is executed and/or feedback is provided to the user at the selected AI appliance (step 640), for example, at the detecting AI appliances or an application. The application can be embedded in an AI appliance or be a remotely located service (e.g., a cloud-based application).

FIG. 7 is a more detailed flow diagram illustrating the step 610 of detecting an event through different sensors at one or more AI appliances of the method 600 of FIG. 6, according to one embodiment. Ambient audio is continuously stored in a memory element (step 710). An audio volume (or other characteristic) above a predetermine intensity for a minimum duration is detected (720), as indicative of a possible event. The stored ambient audio is framed for a certain duration (e.g., a duration above the predetermined intensity, or a sample thereof) (step 730). An audio file is generated from the framed ambient audio (e.g., compressed audio file suitable for network transmission) (step 740).

FIG. 8 is a more detailed flow diagram illustrating the step 630 of analyzing multi-sensor data to determine a response command of the method 600 of FIG. 6, according to one embodiment. Event data is received (step 810). An event is identified from the event data by comparing an event audio file to a table or records of known audio files (step 820). A location of the event is estimated (step 830). Finally, a response command corresponding to known audio files in view of the estimated location is looked-up (step 840)

FIG. 9 is a flow diagram illustrating an example method for providing home automation by using AI appliances for establishing an audio connection between users within an AI environment, according to one embodiment.

Location information for AI clients is stored (step 910). Each AI client can self-report a location once affixed to an outlet or another base. In another embodiment, a scanner with GPS capability can report locations by scanning an AI client for identification and attaching location data for uploading. Alternatively, a network administrator can provide or link a database of locations in association with AI client identifications.

Audio event data is detected for user A (step 920). A processor determines that the audio event data comprises a request for audio connection with user B. As described above, sensor data from a detected event can be sent to a resource for analysis (e.g., an AI gateway). Based on the analysis, a command is sent for execution at a selected AI client. In this case, “Call Laila” is processed by the AI gateway and a connection request is sent to one or more AI clients nearby an estimated location of user B. The connection request may be a human voice interface that alerts user B of who is attempting to connect. There can also be a quick voice message from user A describing a purpose of the call.

To configure a call, a location of user B is estimated (step 930). The estimated location can be a last known location. The estimated location can also be triangulated from one or more events observed by AI clients. A user is identified based on AI applied to biometric and/or non-biometric observations such as, voice recognition, walking patterns or other patterns, habits, personal items recognized by sound (e.g., electric shaver for household of one adult male, or a ring tone of a telephone), a sequence of events (e.g., a personal wake up alarm, followed by a shower in the same room, followed by footsteps to the kitchen), and any other type of personal identifier. More weight can be given to biometric matches, and some implementations may require at least one biometric match before performing sensitive AI actions with a user. In one embodiment, a probability is calculated that a detected user matches a user in the database by comparing detected identity information against collected identity information for all users registered with the system. User identification in an implementation is updated by continuously tracking the user and analyzing new events in combination with earlier events. An identity can be updated or corrected as more information is collected.

Establishing an audio connection between user A and user B (step 940). The audio connection is based on location data. In one form, a closest AI client can activate a speaker and microphone to facilitate a call. In one example, a first microphone of the first AI client is connected to a second speaker of the second AI client and a second microphone of the second AI client to a first speaker of the first AI client, corresponding to locations of first and second users. In another form, several AI clients are balanced with respect to volume to give and receive a more robust sounding sound. An AI gateway sends commands to AI clients for execution.

Note that intelligent, and dynamically updated call connections are merely one application of AI actions and interactions leveraged from knowing who is in an AI environment and where they are. AI actions specific to a user and/or specific to a location are also possible.

Responsive to updated location information for either user A or user B, adjusting the audio connection between user A and user B (step 950). For example, a user A walks around a room completing errands, location coordinates change as new triangulation data becomes available. The audio connection can be updated in real-time with estimated location. In other cases, a change in ambient conditions (e.g., background noise) or other conditions can also result in adjustments to the audio connection.

IV. Generic Computing Device (FIG. 10)

FIG. 10 is a block diagram illustrating an exemplary computing device 1000 for use in the system 400 of FIG. 4, according to one embodiment. The computing device 1000 is an exemplary device that is implementable for each of the components of the system 100, including the AI gateway 420 and the AI server 410. The computing device 1000 can be a mobile computing device, a laptop device, a smartphone, a tablet device, a phablet device, a video game console, a personal computing device, a stationary computing device, a server blade, an Internet appliance, a virtual computing device, a distributed computing device, a cloud-based computing device, or any appropriate processor-driven device.

Many of the functionalities described herein can be implemented with computer software, computer hardware, or a combination.

Computer software products (e.g., non-transitory computer products storing source code) may be written in any of various suitable programming languages, such as C, C++, C#, Oracle® Java, JavaScript, PHP, Python, Perl, Ruby, AJAX, and Adobe® Flash®. The computer software product may be an independent application with data input and data display modules. Alternatively, the computer software products may be classes that are instantiated as distributed objects. The computer software products may also be component software such as Java Beans (from Sun Microsystems) or Enterprise Java Beans (EJB from Sun Microsystems).

Furthermore, the computer that is running the previously mentioned computer software may be connected to a network and may interface to other computers using this network. The network may be on an intranet or the Internet, among others. The network may be a wired network (e.g., using copper), telephone network, packet network, an optical network (e.g., using optical fiber), or a wireless network, or any combination of these. For example, data and other information may be passed between the computer and components (or steps) of a system of the invention using a wireless network using a protocol such as Wi-Fi (IEEE standards 802.11, 802.11a, 802.11b, 802.11e, 802.11g, 802.11i, 802.11n, and 802.11ac, just to name a few examples). For example, signals from a computer may be transferred, at least in part, wirelessly to components or other computers.

In an embodiment, with a Web browser executing on a computer workstation system, a user accesses a system on the World Wide Web (WWW) through a network such as the Internet. The Web browser is used to download web pages or other content in various formats including HTML, XML, text, PDF, and postscript, and may be used to upload information to other parts of the system. The Web browser may use uniform resource identifiers (URLs) to identify resources on the Web and hypertext transfer protocol (HTTP) in transferring files on the Web.

V. Additional Embodiments

Many additional techniques are possible in conjunction with the system described herein. One technique concerns set-up. Once out of the packaging, accounts are configured for the system 100 (e.g., on the AI gateway 420), and partner accounts are set-up for compatibility. AI clients are plugged into the wall, lamps, and otherwise, at geographically dispersed locations. Once paired with an access point or home router, a human voice interface can guide set-up at one or any of the AI clients, or optionally through a PC. Natural conversation is preferably used for set up by asking the user questions, such as “What room am I in?”, “Who am I talking to?”, “Are any other users around?”, “What was the cause of that loud noise?” Biometric identifications are generated from voice and other ambient conditions (e.g., walking sound, coughing, etc.). Responses allow unique biometric information to be collected for identification of users at a different time. Each individual AI can be set-up, along with a system-wide set-up and calibration.

Another technique involves different AI interfaces based from an AI device inside the network, a network edge, and from the cloud. There can be many, separate human voice interfaces, with independent processes and preferences. Different human voice interfaces can serve the system as a whole, each user, each AI appliance, or each service (e.g., telephone calls). For example, an interface named Alice with a distinctive voice can track a specific user around the system, and other users can adapt to tune out Alice's voice. Information can be kept to a particular interface or submitted for global use. AI appliances on the edge, such as user telephone when away from home, or a smart car can also have unique interface actions.

Yet another technique provides a hub for all external AI services. In more detail, the system can analyze a request and match the request to an AI system or non-AI system having the appropriate capability to respond the request (e.g., Alexa, Google Now, Google Search, Viv, Siri, and Cortana). In one case, if an instant message is requested to be sent to a friend, the system can recognize that Facebook Messenger is the preferred or only communication channel between the two friends. The voice sample is translated to text and then encapsulated using a Facebook Messenger API and sent to a Facebook gateway for further processing. An acknowledgment of success can be sent back downstream and output from a nearby AI device.

Additionally, a dynamic ambient condition sensor can modify actions of the system based on context. This allows each interaction with a user to be unique and optimized. Knowing condition of the room and the identity of the user prior to feedback improves the timing, mechanism, intensity, and the like for feedback. Conditions can also include noise level, amount of light, other nearby users, temperature, other system activities, and more. For instance, feedback in a living room with a loud television at 2 PM can be different from feedback in a baby room at 2 AM.
